Hi, I brought a 300C 3 months ago and have had a problem

Customer Question

Hi,

I brought a 300C 3 months ago and have had a problem with sudden power loss (car dies)

This happen on 2/3 occasions at low speed. No warning lights or any error message
I am under warranty and took the car back to the garage.....

They hooked it up but could find no faults - they did find a split in a fuel line to the fuel pump which was replaced.....

I took the car back and ok until 3 weeks later the car died again.

V frightening this time as it was at 25mph and my wife and kids in the car...

Again no warning lights and the car would start as normal imedialtely afterwards...

The dealership have now collected the car from my house as I wont drive it...

Dont know what to do if they say they cant find another fault....

AA say I would have to find the fault to get anywhere in terms of refund etc...

Hi,my name is mike and I will assist you with your question.
The issue that you are describing is consistent with the electric fuel pump electrically shorting and causing the issue. This can be hard to diagnose since the pump has not completely failed. What the shop needs to do is connect a scan tool to the vehicle that is capable of monitoring the fuel pressure while driving.
